Letters Patent No. 101,168, dated March 22, 184'9.

To all whom it may conce/rn 33e it known that I, G. F'. SCHUL'ZE, ot'Janesville, in the county of Rock and .State of Wisconsin, haveVentilating Houses; and I do hereby declare the folwbich myiuventionappertains to make and use the same, reference being han rc theaccompanying drawings forming part ot' this specification, in which theligure is a vertical section ot' a room illustrating my Myinveution hasfor its object to more thoroughly heat dwelling and other houses, withgreater economy of fuel than is now the case. .The primitive method oiheating was by an open While luxury has preserved the latter, economyhas in progress by the common stove, which possesses the merit ofradiating the heat from all sides. Without pensive medium forheatingpurposes.

The common stove radiates the heat but a shortdiately surrounding it,which, as it becomes heated, is rareed, andascends, and is followed by acurrent of cold air -from the floor ofthe room. This,viu its turn,

current of heat-ed air.V This current, however, is either limited to anarrow space immediately surrounding the stove, leaving the remote partsof the room cold and uncomfortable, or tilis the upper part of the roomonly,

the feet are surroundedby cold air, while the head and upper parts of'the body are exposed to' a dry, hot

temperature. y e These defects in the method of heating by the coni-Diienlties in conveying heated air from the furnace to the rooms causedthe discovery that, to introduce a quantity ot heatedair into a room,the expulsion of the same quantity of the air already in the room be .Goi' the room.

The Schedule referred'to in `these Letters Patient-and making par: ofthesame,

ing became confounded, so that about the saine quam tity of partiallycooled air is now withdrawn and wasted from a dwelling with i'ewoccupants, not for ventila` tion, but in order t'o 'warm the same, as.is expelled from an eqnal-sized dwelling with rnanyocculmncs, when `theexpiilsion may be justied on accountof ventilation.

This leads to the inquiry why -uuvitiatnd and only partially-cooledairis wasted. This partially-cooled air is much warmer than that outsidethe dwelling, and should be returned to the furnace and reheated,instead of heating the extreme cold air from without.

My invention, therefore, consists in producing a cir culation of heatedair from a heater or furnace through the space to he heated, and, afterbeing partially deprived of its caloric, back to the furnace to bereheated, the circulation being-continued indeiinitely, l

oruntil the air becomes vitinted, when it is'di schal-geil, and freshair introduced.

lThe accompanying drawings represent the section of a dwellinghouse,.o`which` A is a room;

E, the floor;

C, the ceiling; y

D, the ceiling of a lo'werroom; and

E, an outside wall.

The i'ioor B is raised slightly above the lower cells ing l), to leavean air-space, F, between them, which communicates at one 'end with theroom A, and at theother end with the liuc or chimney, G.

H is a hollow cylinder, open at 'both ends, placed vertically within theroom A surrounding tile stove, furnace, or other heater I, andcommunicating at its lower end with the space F' beneath the floor.

J is a pipe connecting the interior of the cylinder with the outer air,or arranged in any suitable manner to supply cold airto the heater whendesired.

It is provided with a valve or damper, a, by which V the supply oi' coldairis introduced or ont oii.

b'is also a valve or register in the due G, by which communication isopened or closed between the space F and said tine G. The smoke andproducts oi' combustion are discharged from the heater into the flue Ghy means ol' the pipe K, in the usual. manner.

The operation is as follows:

As ting furnace l becomes heated, the air within the cylinder 'H is alsoheated, and rises against theceiling This is i'ollowed hya current ofcold air from the space Fwhich, in its turn, also rises, andis'discliarged through the cylinder into the room rlhe heated air soescaping from the cylinderiuoves along the ceiling C to the outside wallE, and in its passage becomes cooled suliciently to cause it to desecond "lo the Hoi-r, beneath which it is allowed to pass bach.agairnto' the heater, tol be rebeatetf and again discharged Vin'tortheroom. -By this means n constant circulation is produced i-n thedirection of the arrows, thoroughly warming all parts of .the room.

When the air becomes vitiated, the valve .a ln the supply-piped and thevalve b in the ue G are opened, the formerto admit fresh air around' theheater, and

the latter to permitthe discharge of vitiated air from Suc-h.

the room Athrough the space F into the flue.` 'vitiated aii' is causedto ascend the ue, as shown by A,the arrows, being heated by'contact withthel pipe Kl yfrom the heater. These operations are continuedalternately, as will be `1`feadily understood."r

It must, however, be borne in mind that the heating of the room iscontinued during the Ventilating process, so that it will not besubjectedl to sudden changes in temperature.

. 'Several rooms may be heated by my improved system from the sameheater, which may-be placed in `any preferredv story of the dwelling. orother structure.

It is requisite,I however, to connect the room to be warmed with the topof the cylinder surrounding the heater. and the space below the floorwith the bottom -heater within the rooni to be heated, for the purposeV'of causing a constant circulation of heated air from the furnacethrough ithe space to be heated, and, utter being partially deprived ofits caloric, back-tothe` l heater to be reheated, continuingindefinitely, in combination with a Ventilating process by which thevitiated air is expelled ii'om the room, or roomsyand cold airintroduced, during the operation of warming, as herein shown anddescribed. l u y G.
